Abstract
The reaction of 4,4'-dihydroxydiphenl methane (4,4'-DPM) with glycidyl methacrylate (GMA) catalyzed by triethylbenzyl ammonium chloride (TEBAC) has been studied for the purpose of synthesis of electron beam curable prepolymer. The reaction was in good agreement with third-order kinetics. according to -d[GMA]/dt=k[TEBAC][DPM][GMA] and the apparent activation energy was about 33.4kca1/mole. However, the reaction rates were increased if tile reaction proceeded after the mixtures exposed to air for 24 hrs at room temperature. The effects of the catalyst and the difference in the reactivity between 2.2'-DPM to GMA were discussed. The plausible reaction mechanism was proposed on basis of experimental data obtained.
